From what I've seen, the Conversion Kits are available in the US but not in the EU. I'm unfortunately stuck with the GF Modern Combat Ultimate Stick because i couldn't afford to buy both at the same time, while shortly after the purchase the Mk. IV was announced :/ . Seeing that you can maybe use so...

Im sorry to ask but when does the next batch of the GUNFIGHTER MK.III BASE arrive, if it hasnt arrived in the last weeks already?
